Air pollution damages materials, but it has changed dramatically in the past century, with a reduction in the concentration of corrosive primary pollutants in urban atmospheres. At the same time, architectural styles and types of materials have changed, as we have moved to more organically rich, photochemically active atmospheres. Contemporary air pollutants have the potential to degrade organic coatings and polymers, which are of great importance to modern structures, while increasing amounts of fine diesel soot spoil the simple lines and smooth areas characteristic of many modern buildings. This book examines a range of materials, discussing the ways in which they are likely to be damaged by air pollutants. It should be of interest to scientists and policymakers dealing with the effects of urban air pollution.

This book contains twenty-one original papers and one review paper published by internationally recognized experts in the Atmosphere Special Issue "Recent Advances in Urban Ventilation Assessment and Flow Modelling", years 2017–2019. The Special Issue includes contributions on recent experimental and modelling works, techniques, and developments mainly tailored to the assessment of urban ventilation on flow and pollutant dispersion in cities. The study of ventilation is of critical importance, as it addresses the capacity with which a built urban structure is capable of replacing the polluted air with ambient fresh air. Here, ventilation is recognized as a transport process that improves local microclimate and air quality and closely relates to the term “breathability”. The efficiency with which street canyon ventilation occurs depends on the complex interaction between the atmospheric boundary layer flow and the local urban morphology. The individual contributions to this Issue are summarized and categorized into four broad topics: (1) outdoor ventilation efficiency and application/development of ventilation indices, (2) relationship between indoor and outdoor ventilation, (3) effects of urban morphology and obstacles to ventilation, and (4) ventilation modelling in realistic urban districts. The results and approaches presented and proposed will be of great interest to experimentalists and modelers, and may constitute a starting point for the improvement of numerical simulations of flow and pollutant dispersion in the urban environment, for the development of simulation tools, and for the implementation of mitigation strategies.

Urban areas are major sources of air pollution. Pollutant emissions affecting air quality in cities are considered to have adverse consequences for human health. Public and government concern about environmental issues arising from urban air pollution has increased over the last decades. The urban air pollution problem is widespread throughout the world and it is important to find ways of eliminating or at least reducing the risks for human health. The fundamentals of the physical and chemical processes occurring during air pollutant transport in the atmosphere are nowadays understood to a large extent. In particular, modelling of such processes has experienced a remarkable growth in the last decades. Monitoring capabilities have also improved markedly in the most urban areas around the world. However, neither modelling nor monitoring can solve urban air pollution problems, as they are only a first step in improving useful information for future regulations. The defining of efficient control strategies can not be achieved without a clear knowledge of the complete pollution process, i.e. emission, atmospheric transport and transformation, and deposition at the receptor. Improving our ability to establish valid urban scale source-receptor relation ships has been the objective of SA TURN, one of the 14 subprojects of EURO TRAC-2. Similar to the other subprojects of this co-ordinated environmental pro ject within the EUREKA initiative, SA TURN brought together international groups of scientists to work on problems directly related to atmospheric chemistry and physics. The present volume summarises the scientific results of SATURN.

Numerical Evaluation Of Wind Induced Dispersion Of Pollutants Around Buildings written by Ye Li and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1998 with Air categories.

A detailed and comprehensive numerical study of wind-induced pollutant dispersion around buildings has been carried out. Research in this area was reviewed and analyzed. The results from various studies were compared. Based on the review and the comparison with various studies, a more effective methodology for the numerical evaluation of dispersion of pollutants around buildings has been proposed. Computed results of a two-layer approach show various degrees of improvement for the concentration field in the wake region and on the back wall of the building. Results from two-layer approach also show improvement on the building roof for along-wind direction. However, the two-layer approach does not seem to work well for roof concentration along the cross-wind direction; this is probably due to the drawback of the isotropic turbulence model used. The previous numerical studies on pollutant dispersion around rectangular buildings only investigated the concentration profiles for along-wind direction or vertical direction, and these were only for limited situations. A systematic examination of pollutant concentration in the wake of a rectangular building has been carried out for two different release sources. The concentration profiles have been investigated for along-wind, across-wind and vertical directions for various locations. The numerical simulation results have been compared with those from the experiments and from the Modified Gaussian Model. Results from numerical simulation generally agree well with those from the experiments. It was found that the numerical simulation predicts ground level pollutant concentrations better than the Modified Gaussian Model in the near building wake area. The influence of numerical errors on the computed results and the effects of thresholds in the demoralization and convergence process have been investigated for the first time in the area of numerical simulation of pollutant dispersion around buildings.

Air quality and air pollution control are tasks of international concern as, for one, air pollutants do not refrain from crossing borders and, for another, industrial plants and motor vehicles which emit air pollutants are in widespread use today. In a number of the world's expanding cities smog situations are a frequent occurrence due to the number and emission-intensity of air pollution sources. Polluted air causes annoy ances and can, when it occurs in high concentrations in these cities, constitute a seri ous health hazard. How important clean air is to life becomes apparent when consid ering the fact that humans can do without food for up to 40 days, without air, how ever, only a few minutes. The first step towards improving the air quality situation is the awareness that a sound environment is as much to be aspired for as the development of new tech nologies improving the standard of living. Technical progress should be judged es pecially by how environmentally benign, clean and noiseless its products are. Of these elements, clean air is of special concern to me. I hope that this book will awaken more interest in this matter and that it will lead to new impulses. Due to the increasing complexity of today's machinery and industrial processes science and technology can no longer do without highly specialized design engineers and opera tors. Environmental processes, however, are highly interdependent and interlinked.
